THE CONSTRUCTION METHOD OF MULTICOMPOSITE RAHMEN BRIDGE

摘要

The present invention relates to a construction method for a composite rigid-frame bridge and, more specifically, to a construction method for a composite rigid-frame bridge, which has excellent constructability and rigidity by constructing a rigid-frame bridge after removing negative moment due to dead load of a girder and a slab. The construction method for a composite rigid-frame bridge comprises: a step of constructing a composite girder by compositing an I-shaped steel frame girder in which an upper hinge plate is installed on the bottom at both ends and the concrete panel; a step of placing wall concrete performing a role of an abutment; a step of mounting a lower hinge plate in the upper part of the wall concrete; a step of installing a hinge shaft in the lower hinge plate; a step of installing the composite girder in order for the lower hinge plate having the hinge shaft to correspond to the upper hinge plate; and a step of forming the bottom plate by placing reinforced concrete in a rest part of an I-girder, the hinge shaft, and the upper and lower hinge plates.
